Audi TT plug-in hybrid offroad concept: 148mpgApril 25, 2014
The Audi TT plug-in-hybrid offroad concept is a cross between a coupe and an SUV – as well as being a plug-in hybrid that promises 148mpg.
The plug-in hybrid drive in the Audi TT offroad concept delivers 408PS of system output and 650 Nm of system torque. The show car accelerates from 0 to 62mph in 5.2 seconds yet also has the potential for 148.6mpg, equating to a CO2 output of 45g/km CO2.
It can travel for over 30 miles solely on electric power and zero local emissions, and has a total range of up to 546 miles.
The combustion engine is a four-cylinder, 2.0-litre TFSI producing 292PS and 380 Nm of torque. Mounted on the rear axle of the Audi TT offroad concept is a second electric motor producing a maximum of 85 kW and 270 Nm. In front of the rear axle is a liquid-cooled, lithium-ion battery.
The show car is also designed for use with Audi Wireless Charging technology for contactless inductive charging.
The Audi drive select management system offers three driving modes. EV mode gives priority to electric driving. In this case, the front drive unit is inactive, and the electric motor at the rear axle can rapidly accelerate the four-door car to a maximum of 80mph.
In Hybrid mode, all three drive systems work together in various ways as necessary. In many situations the front electric motor assumes the role of a generator. Powered by the engine, it recharges the battery and thus extends the electric range.
Full system output is available in Sport mode. During “boosting,” i.e. strong acceleration, the rear electric motor works together with the TFSI petrol engine.
The driver can use the “Hold” and “Charge” functions in the MMI system to specifically influence the battery’s charge state, e.g. to increase storage of electric energy so that it can be used over the final miles to the destination.
The Audi TT offroad concept is making its world public debut at the Beijing Automotive Exhibition.
